LIGHTING FIXTURE.

Application filed July 13, 1925. Serial No. 43,092.

My invention relates to that class of units which are enclosed, so as toeliminate the collection of dust, dirt, bugs, etc., on the bottom of theglobe, and yet to produce an eflicient unit which will be highlybrilliant, without any glare. I

My invention consists of certain details of construction hereinafter setforth and illustrated in the I accompanying drawings, in which V Fig. 1is a side elevation of my improved lighting fixture having aportion ofthe reflecting surface of the canopy broken away to show the interiorconstruction;

Fig. 2 is a detail view of the mounting for holding the globe inposition.

Similar reference numerals refer to similar parts throughout the entiredescription.

As shown in the drawings, my improved lighting fixture unit may besuspended from a chain 1, and attached to the ceiling canopy 2, in theusual manner. At the lower end of the chain 1 is mounted a holder 3ofstandard construction. To this holder, I secure an enclosed globe 4.This globe is constructed, as clearly seen in the drawings, of twoparallel ribs 5 and 6, which are con nected together by downwardly andinwardly tapering side walls 7. The bottom is closed by convex member 8'and the top is formed by an inwardly extended truncated conoidal portion9. The reflector canopy 10 is provided with a substantially horizontalreflecting surface 11, in the central portion of which an opening 12 isformed, which permits the upper portion of the truncated conoidalportion 9 of the globe'to project through, to permit the light rays toilluminate the ceiling, though it may be located just below thereflector.

The reflector is held in position by means of three straps 13 which areproperly located equidistant from each other, and are secured to theholder 3, so as to suspend the canopy 10 therefrom, without letting itsweight rest upon the glass globe.

The globe 4 which is preferably formed of translucent glass does notinterfere with the efliciency of the unit as a light giver but doesentirely minimize the glare which reflector, thus utilizing a largenumber of these rays which would otherwise be lost on the ceiling. 'Atthe same time, by permitting a small portion of the truncated conoidalpart of the globe to extend through the canopy, it will, as indicated bythe lines in the drawing, throw suflicient direct light above the canopyreflector to efle'ctually' re-' move all sense of gloomor darkness abovethe unit, and yet does not sacrifice enoughof the reflecting surface tomaterially interfere with the efliciency of the unit as a whole. 1

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is:

1. A lighting fixture, comprising a hanger, an enclosed cylindricalglobe having parallel ribs at the top and bottom, and downwardly andinwardly tapering side walls, and an inwardly extending truncatedconoidal portion which extends from the upper rib to stantiallyhorizontal reflecting surface which reflectsthe light rays to theworking plane, there being a central opening in said reflector throughwhich said-conoidal portion extends, to illuminate the ceiling.

2. A lighting fixture, comprising a hanger, an enclosed cylindricalglobe having parallel ribs at the top and bottom,and downwardly andinwardly tapering side walls, and an inwardly extending truncatedconoidal portion which extends from the upper rib to the hanger, acanopy reflector, having a subthe hanger, a canopy reflector, having asubstantially horizontal reflecting surface which reflects the lightrays to the working plane, I

there being a central opening in said reflector to permit the light raysfrom the truncated conoiclal portion to illuminate the ceiling.

5 3. The combination With a canopy, having a substantially horizontalreflecting surface of an enclosed globe, the sides of which taperdownwardly, the upper part of which comprises an inwardly extendingtruncated conoidal portion there being an opening in 10 the central partof said canopy through which the light rays from the conoidal portionmay illuminate the ceiling.
